Canon EF 70-300mm f/4-5.6L IS USM

Manufacturer description: Designed to deliver ultra-high quality images along with lightning fast operation, the new Canon EF 70-300 f/4-5.6L IS USM telephoto zoom lens brings a favorite zoom range to the celebrated Canon L-series of lenses. It features two Ultra Low Dispersion (UD) elements for improved image quality and reduced chromatic aberration, incorporates a floating focusing mechanism for sharpness from close up to infinity, plus an IS system that increases usability by approximately four stops. The Image Stabilization system also features a function that allows it to continue to operate, even when used on a rigid tripod. An optional Canon Tripod Mount C (W II) is available as an accessory, for balanced mounting on a tripod or monopod. Gleaming white on its exterior, the lens is dust- and water-resistant, and now also features a newly-developed Fluorine coating that resists smears and fingerprints, and significantly eases lens cleaning. For any serious and critical EOS user, this new L-series lens represents an excellent -- and portable -- solution to versatile telephoto lens shooting.
